Littelfuse FLSR025 - RK5 Time-Delay Fuse 25A 600V (200kA AIC)

Littelfuse FLSR025 is a UL Class RK5 dual-element time-delay fuse designed for overcurrent protection in industrial electrical systems. Rated for 600V AC/DC applications with a 25A current capacity, it features a 200kA interrupting rating at 600V for high-fault protection. The fuse measures 5 inches in length with a 0.81-inch diameter barrel constructed to UL 248-12 Class RK5 standards. It carries CE, CSA, and QPL-W-F-1814 certifications for compliance with international safety requirements. Typical applications include motor branch circuits, transformers, and power distribution equipment where time-delay characteristics prevent nuisance tripping during temporary inrush currents.
